At times, you may get a bug report that describes exactly the way that you think the program should work in other words, a bug that isn t a bug. For example, an e-mail program could be set up to automatically send forged nondelivery reports to a spam folder. A user who wasn t expecting this might report the action as a bug. In that case, By Design would be the most appropriate way to close the bug. Be careful when using this resolution, though; if something works as you designed, but not as end users expect, it might be time to change your design. Alternatively, you might make a note to explicitly spell out this bit of design in the application s documentation.

We now receive the actual HRESULT returned from the COM method. Also note that request 3 returns an error HRESULT that would normally be marshaled as an exception. However, after these changes, no exception is thrown. Instead, we now take full responsibility for checking the HRESULT after each call to this COM method.

This greatly simplifies the use of this function for all other managed code. It allows us to write code that is much more descriptive and less error-prone. For example, consider this code: if(status == CustomerStatus.PastDue) or if(status == 3) Which code would you rather read Which code is self-describing Which code will be easier to modify years from now once the original developer has moved on to greener pastures The sample wrapper also uses an enumerated type for the custType input parameter. This allows you to validate the input value against a set of named values, eliminating the chance of passing an invalid magic number to the function. You won t have to wonder if a corporate customer is a type 2122 or a 2123, because you ll have an enum type that defines the acceptable values.

If counter A had incremented to, say, 123 liters, the first four characters on the bottom row of the display would read "123L" Resetting the counter without clearing the display would subsequently cause the value 0L to be written to the first two characters of the display, but the third and fourth characters wouldn't be altered The result is that the display would end up reading "0L3L," which wouldn't make much sense Overwriting those positions in the display with 0L followed by six spaces prevents this from happening The same thing is done for counter B, but of course we first set the cursor to position 8 (actually the ninth character on that row since it starts from 0) before writing it out void loop() { if(digitalRead(resetButtonA) == LOW) { totalMilliLitresA = 0; lcdsetCursor(0, 1); lcdprint("0L "); } if(digitalRead(resetButtonB) == LOW) { totalMilliLitresB = 0; lcd.

See recipes 1-9 (Using C++ Interop As a Managed Wrapper) and 1-13 (Securing Access to Unmanaged Code).

setCursor(8, 1); lcdprint("0L "); } The status LED is illuminated if either of the counter reset buttons is pressed, so we then check if either button is pressed and set the status LED to LOW (on) or HIGH (off) appropriately if( (digitalRead(resetButtonA) == LOW) || (digitalRead(resetButtonB) == LOW) ) { digitalWrite(statusLed, LOW); } else { digitalWrite(statusLed, HIGH); } The main loop spins through very fast and we don't want to do all the input processing every time through because we need to average the number of pulses across one second, so the rest of the main loop code is wrapped in a check to see if at least one second has passed since the last time it was.

Sometimes, the best way to resolve a bug is to fix it. In fact, if testers are doing their job well, this will probably be the most common bug resolution in the system.

Modify the managed function declaration to specify a different calling convention. Use the CallingConvention field of the DllImport attribute. For example, consider this unmanaged function declaration: extern "C" __declspec(dllexport) int __cdecl AddSomeNumbers(int numOne, int numTwo); To specify that this function should be invoked with the cdecl calling convention, you declare the function like this in C#: [DllImport("FlatAPILib.DLL", CallingConvention=CallingConvention.Cdecl)] public static extern int AddSomeNumbers(int myNumA, int myNumB); The same declaration in a Visual Basic .NET module looks like this: <DllImport("FlatAPILib.DLL", _ CallingConvention:=CallingConvention.Cdecl)> _ Public Function AddSomeNumbers( _ ByVal myNumA As Integer, ByVal myNumB As Integer) _ As Integer End Function
